TLDR: I quit Elastic Beanstalk because they deploy on weekends and won't clean up their mistakes. And Beanstalk is far too buggy for a 9 year old service.

I struggled to get Elastic Beanstalk working well. The documentation is incomplete.

The Elastic Beanstalk console often shows servers as up when they're really down.

Once, my Elastic Beanstalk deployment stopped writing log files. After wasting many hours debugging, I went to AWS Loft and consulted with the support engineer. He had me log into the backing EC2 instance and debug. I was using Elastic Beanstalk so I would never have to log in to EC2 instances. He concluded that the application logs were not appearing due to a bug in the service. He promised to file a bug report.

The last straw was when Elastic Beanstalk team deployed a broken API on a Saturday. THEY DEPLOYED ON A SATURDAY!!! Their broken API added an invalid entry into the beanstalk config database for my account. All subsequent calls to the Beanstalk API failed with a 500 Server Error. I paid for an AWS Support subscription and filed a ticket. Their support engineer told me to install the AWS CLI and run some obscure commands to remove the invalid entry which their botched API deployment added. I asked them to do it and they refused. So I migrated off of Elastic Beanstalk to Docker. I have since migrated off AWS to Digital Ocean.
